2011 Roo 21RS loud fridge fan

WannaBcamping · 07-11-2015, 06:34 PM

Is it common in Roos for the fridge fan to cycle on and off every 3 to 5 minutes? It is a rather loud humming sound when it is on. Is this normal also? Why does it cycle so often? Is this is an indication of a problem?

Are you sure it's not the converter fan?

WannaBcamping · 07-11-2015, 09:02 PM

No we're pretty sure it's coming from the fridge.

WannaBcamping · 07-11-2015, 09:04 PM

On second thought it could be the converter fan after all.

Then it's probably due to a low or bad 12v battery.

Just a quick question, Do the Refrigerators in these have a fan?

Some do some don't have fans.
The converter fan comes on due to high load.
Lots of lights on or a bad battery is possible.

If it's the fridge fan,,,,then your fridge is installed on a slide. Go outside and put your ear to the lower fridge vent. If it's louder,,,,that's what it is. It comes on when the condenser outside needs to cool down. Without it, you'd have no refrigeration. You don't normally see them on fridges that aren't on a slide, because the condenser heat leaves more easily out the top vent.

Only slide we have is the rear bed. Fridge is to the left right as you enter trailer. Hubby took off the outside access panel (which is to left of entry door outside). He looked up into it and there are 2 fridge fans which are either the same as computer fans or at least look like them. It is definitely them cycling on and off frequently. Its not freight train loud but it is noticeable and annoying.

So question is: is it really normal for them to cycle on so frequently?

We are under the 1st year of warranty so maybe we can get them replaced for quieter ones or at the least we'll have it looked at.

We have a rockwood & took ours in for a warranty issue related to this same issue. The dealer said they noticed nothing wrong, the sound was normal. 😕

My 2011 21BH had a pretty loud fridge fan. The new 183 is nice and quiet.

Cathy,,,,yes they DO look like computer fans and they DO cycle off and on frequently......mine is on right now and it'll go off in a while....then back on........just like the electric fan on some foreign cars for their rediators. It's built that way. It'll cycle on more if you're in the warmer climates of the country. I'm in Texas and it's expected to run like that. Somebody on this thread months ago said he cut the wires on his. Don't do that! It'd be like putting a piece of cardboard on your car radiator and expect the car not to overheat. It'll kill the efficiency and shorten the life of your refridge. I was in the AC/heating/ and refrigeration business for 40 years before I retired,,,,,I know what I'm talking about. Eventually you'll get used to the sound. If you DON'T hear it, it's because it's cold outside and not calling to come on or the fan is bad and you'll need to replace it.

I have a different model but the same problem. Several owners have replaced the factory fans with quieter computer fans. That is what I am having done. If you do a search, you will find some more info.

Thanks everyone for all the replies!

We had a 2011 ROO 21SS and the converter turned off and on every few minutes when the fridge was on elec power. It bugged us when sleeping.
We turned on the fan on the air conditioner to hide the sound when we slept.

Problem solved.

We traded to a 21BD which has a bigger fridge, and there is no converter
sound.

We have 2011 roo 23ss, the fridge is not in the slide and we "had" a fan in it that cycled on and off allot and we dry camp almost all the time, and it would draw down the batteries way to quick. So i stooped at the original sales dealer when we were passing by over 2 years ago, "we bought it used from a different dealer" i asked why that fan ran so much and a VERY helpful lady in the service department told me in that model it should not have a fan. So she came out and showed me where the in line fuse was, and toke it out. Never put it back in, and never have had a problem! No more fan running using valuable power!

Interesting. Bears looking into. But I would be leary about removing the fan. Actually our 2011 Roo 21RS appears to have 2 of them.

Didn't actually remove the fan, just the fuse. The lady at the dealership said they some times get the wrong fridge coming down the lines and put ones in that belong in slides.

That wouldn't surprise me. Thanks, we'll at least look into this.
